Description

Instead of commercial yeast, this focaccia is made with sourdough starter. Top with cherry tomatoes, olives, and fresh rosemary for maximum Genovese flavor.

Ingredients

2 1/2 cups high-protein bread flour (such as King Arthur Flour®), divided
1 cup water, divided
3/4 cup sourdough starter discard, at room temperature
6 tablespoons extra-virgin olive oil, divided, or as needed
1 teaspoon fine sea salt
1 tablespoon water
12 pitted green olives
6 cherry tomatoes, halved
1 sprig fresh rosemary
1/2 teaspoon flaked salt

Directions

1 Mix 1/2 cup bread flour, 1/4 cup water, and sourdough discard together with a wooden spoon. Add a little flour to the bowl of a stand mixer. Add starter mixture and allow to rise in a warm area, without direct sunlight, until doubled in size, about 2 hours.
2 Attach dough hook and begin to mix the starter. Add remaining flour, 3 tablespoons oil, and 1 teaspoon salt. Mix in enough of the remaining water until dough pulls from the sides of the bowl and forms a ball; you may not need the full 3/4 cup. Knead dough in the mixer for 5 minutes.
3 Transfer dough to a work surface and knead by hand for 5 minutes. Score and cover with a cloth. Allow to rise in a draft-free place until doubled in volume, at least 2 hours, and up to overnight.
4 Lightly oil a shallow 12x16-inch baking pan. Knead dough for 5 minutes. Spread into the pan using your hands. Whisk 1 tablespoon oil and 1 tablespoon water together. Sprinkle a little bit over the focaccia. Cover with plastic wrap and let rise until doubled in height.
5 Preheat the oven to 400 degrees F (200 degrees C).
6 Push into the focaccia with your fingertips, leaving indentations about 1 1/2 inches apart. Evenly distribute olives and cherry tomatoes on top, pushing them into the dough. Sprinkle rosemary leaves and flaked salt on top. Sprinkle a little more of the oil-water mixture on top.
7 Bake in the preheated oven until browned and cooked through, 20 to 25 minutes. Drizzle olive oil on top before serving.
